3 个解决方案

#1

You could use simple if-check to handle the pausing. Try this:

您可以使用简单的if-check来处理暂停。试试这个:

MediaPlayer mp = MediaPlayer.create(this, Uri.parse(Environment.getExternalStorageDirectory().getPath()+ "/Music/jaihind.mp3"));
if(mp.isPlaying()) {
    mp.pause();
} else {
    mp.start();
}

Note:

注意:

mp = MediaPlayer.create(...);

is already preparing the MediaPlayer returned, so you cannot call prepare (or its variants) again (and there is no need for onPreparedListener as well).

已经在准备返回的MediaPlayer，因此您不能再次调用准备(或它的变体)(也不需要onPreparedListener)。

#2

I think you have to use this

我认为你必须用这个。

 public class Sound extends Activity{

MediaPlayer mp;

    @Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    mp.release();
}

}

#3

mp.release(); does the trick. [ instead of mp.pause(); ]

mp.release();就可以了。(而不是mp.pause();]
